I'm doing some statistics with my own tools, and this CSV file would be the perfect input data for it. It would allow anyone to get any custom made statistics (in Excel or Google spreadsheets, with analytics solutions, ...).

Some agencies, like 123RF, are already proposing a CSV file like this. It would be great to have it "standardized" across agencies, as it is (IMO) the most logical format to allow contributors to reuse statistics the way it fits them the best.

Another nice feature would be to see which keywords were used to download images. This is maybe a bigger step for Adobe Stock as Fotolia was not proposing those stats. However it would be probably one of the most useful feature.
